Definitions

  • the present invention relates to a distribution device, a distribution method, and a computer program for distributing creative data such as advertisement data to display terminal devices via relay server devices.
  • the present application claims priority based on Japanese Patent Application No. 2006-340236 filed in Japan on December 18, 2006. The contents of the cited application are incorporated in the present application by reference.
  • display devices are seen set up for publicity purposes.
  • This type of display device displays in moving or still pictures advertisement data created illustratively by advertising agencies.
  • the advertisements displayed on such display devices are presented unilaterally to viewers. Even if a viewer wishes to know details about a product being advertised, it is impossible for that viewer to know them on the spot. Advertisers, for their part, are unable to ascertain the effects of the advertisements they have displayed on the display device installed at a given place. In particular, the advertisers are incapable of associating specific places where display devices are installed with the effects of the advertisements being run there.
  • the advertisement data displayed by such display devices is often distributed by distribution servers over networks.
  • the present invention has been devised in order to solve the aforementioned problems and its object is to provide a distribution device, a distribution method, and a computer program for distributing creative data such as advertisement data to display terminal devices on time while reducing the load on distribution devices for distributing such creative data.
  • a distribution device of the present invention distributes creative data to display terminal devices via relay server devices so that the display terminal devices may reproduce the creative data.
  • the relay server devices are made up of normal relay server devices and super relay server devices, the normal relay server devices being capable of distributing the creative data to the display terminal devices and incapable of relaying the creative data to the other relay server devices, the super relay server devices being capable of distributing the creative data to the display terminal devices and to the other relay server devices.
  • the distribution device of the present invention includes: storage means for storing a plurality of the creative data; schedule means for creating at least a play list including reproduction start times of the display terminal devices and acquisition destination data indicating acquisition destinations of the creative data; and communication means for transmitting the play list and the creative data to the display terminal devices via the normal relay server devices and the super relay server devices.
  • the schedule means creates the play list by determining the acquisition destination data in such a manner that the creative data is distributed preferentially to the super relay server devices rather than to the normal relay server devices and that the normal relay server devices acquire the creative data from the super relay server devices.
  • a distribution method of the present invention includes: a step of creating at least a play list including reproduction start times of the display terminal devices and acquisition destination data indicating acquisition destinations of the creative data; and a step of transmitting the play list and the creative data to the display terminal devices via the normal relay server devices and the super relay server devices.
  • the play list creating step creates the play list by determining the acquisition destination data in such a manner that the creative data is distributed preferentially to the super relay server devices rather than to the normal relay server devices and that the normal relay server devices acquire the creative data from the super relay server devices.
  • the present invention provides a computer program for causing a computer to perform the above-described method. According to the present invention, the creative data is distributed preferentially to the super relay server devices rather than to the normal relay server devices, and the normal relay server devices acquire the creative data from the super relay server devices. This reduces the load incurred when the creative data is distributed.
  • the distribution system adopting the present invention is a system in which a distribution device 10 distributes advertisement data to display terminal devices 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h (simply called the display terminal devices 1 as well hereunder) set up at convenience stores CS1-1, CS1-2, ..., CS2-1, CS2-2, etc., via super relay server devices 20 and normal relay server devices 30 over a network.
  • the convenience stores CS1-1 and CS1-2 are illustratively franchisees belonging to the same franchise chain.
  • the display terminal devices 1a, 1b set up at the convenience store CS1-1 reproduce approximately the same advertisement data as the display terminal devices 1c, 1d set up at the convenience store CS1-2.
  • the convenience stores CS2-1 and CS2-2 are illustratively stores belonging to franchise chain different from the franchise chain to which the above-described convenience stores CS1-1 and CS1-2 belongs, and franchisees, respectively.
  • the display terminal devices 1e, 1f set up at the convenience store CS2-1 reproduce approximately the same advertisement data as the display terminal devices 1g, 1h set up at the convenience store CS2-2; this advertisement data is different from that reproduced at the convenience stores CS1-1 and CS1-2.
  • the distribution device 10 manages collectively the advertisement data to be distributed to the display terminal devices 1 via the super relay server devices 20 and normal relay server devices 30 on the network, the distribution device 10 distributing predetermined advertisement data to the individual display terminal devices 1.
  • advertisement data is formed as a collection of creative data formed by moving pictures and audio data for advertising individual products and services.
  • the advertisement data is reproduced by display terminal devices 1 in a temporally continuous manner.
  • the distribution device 10 used in such a distribution system has a service server 11 which creates distribution schedules for distributing predetermined advertisement data to the display terminal devices 1 via the super relay server devices 20 and normal relay server devices 30; and a creative server 16 which stores a plurality of creative data forming the advertisement data.
  • the service server 11 is typically constituted by software and hardware.
  • the service server 11 has a schedule unit 12 which creates play lists by devising schedules for the creative data; and a communication unit 13 which distributes the play lists to the super relay server devices 20 and normal relay server devices 30 subordinate to the communication unit 13.
  • the schedule unit 12 creates play lists dynamically, i.e., in keeping with the network environment currently in effect, for the super relay server devices 20, normal relay server devices 30, and display terminal devices 1 subordinate to the schedule unit 12.
  • Each play list is destined for one of the display terminal devices 1.
  • the play list describes a scene start time representing a reproduction start time and a scene end time representing a reproduction end time regarding each of the creative data, and the location (URL: Uniform Resource Locator) of the creative data in question.
  • the URL used here typically includes a scheme name "http,” a server name //www.aaa.co.jp," and a folder name "contents” or the like, ending with a file name "content1.”
  • the URL is defined so that if creative data cached in different server devices has the same file name, then the creative data constitutes the same data.
  • the URLs denote the acquisition destinations of creative data, the acquisition destinations being described in a manner dispersed among the super relay server devices 20 and normal relay server devices 30. Meanwhile, the scene start times and scene end times are input to the schedule unit 12 regarding each of the creative data based on program schedules.
  • the schedule unit 12 creates these play lists by dynamically changing the URLs of which the default is set for the creative server 16, in such a manner as to disperse the load on the super relay server devices 20 and normal relay server devices 30 in consideration of whether the reproduction star time of each of the creative data and the creative data in question are cached in the super relay server devices 20 and how much load is placed on the super relay server devices 20.
  • the URLs in the play list are dynamically changed, the files named in the URLs are furnished with the creative data of the same content if the names are the same. In this case, even if a path before the file names is changed, the desired creative data is always distributed to the display terminal devices 1.
  • load status e.g., number of connections ⁇ data quantity
  • defect status of the super relay server devices 20 e.g., defect status of the super relay server devices 20
  • the communication unit 13 performs a search for the creative data cached in the normal relay server devices 30 subordinate to the communication unit 13, and
  • the creative server 16 stores in a storage unit a plurality of creative data constituting the advertisement data to be reproduced by this distribution system. Upon distribution of play lists, the creative server 16 transmits the creative data as requested by the super relay server devices 20 and normal relay server devices 30.
  • the distribution device 10 structured as described above creates play lists in such a manner that creative data is distributed preferentially to the super relay server devices 20 rather than to the normal relay server devices 30.
  • the normal relay server devices 30 are each incapable of relaying data to the other normal relay server devices, and are apparatuses to which only the display terminal devices can access. In the example of Fig. 1 , the normal relay server devices 30a, 30b and 30c are subordinate to the super relay server devices 20a and 20b.
  • the normal relay server device 30a cannot connect to the other normal relay server device 30b through 30f.
  • the normal relay server devices 30d, 30e and 30f are subordinate to the super relay server devices 20c and 20d.
  • the normal relay server device 30d cannot connect to the other normal relay server devices 30e, 30f, and 30a through 30c.
  • the number of super relay server devices 20 for distributing advertisement data to the convenience stores CS belonging to the same franchise chain is not limited to the number in Fig. 1 or to any other specific number.
  • the number of normal relay server devices 30 subordinate to the super relay server devices 20 is not limited to the number in Fig. 1 or to any other specific number.
  • the super relay server devices 20 are capable of relaying creative data to the relay server devices 30.
  • the super relay server devices 20 are made up of connection-capable relay server devices, relay-capable server devices, and relay-determined server devices. These super relay server devices 20 are determined by software in terms of their policies for acting as the connection-capable relay server devices, relay-capable server devices, and relay-determined server devices which will be described next.
  • the server relay server devices 20 are also superior to the normal relay server devices 30.
  • the connection-capable relay server devices are the super relay server devices enabled as connectable from the viewpoint of the normal relay server devices 30.
  • the super relay server devices 20a and 20b are the connection-capable relay server devices from the viewpoint of the normal relay server devices 30a, 30b and 30c; the super relay server devices 20c and 20d are not regarded as connection-capable relay server devices.
  • the super relay server devices 20a and 20b are made to act as the connection-capable relay server devices for the normal relay server devices 30a and 30b because, with the normal relay server devices 30a and 30b connected to the display terminal devices 1a through 1d at the convenience stores CS1-1 and CS1-2 and subordinate to the super relay server devices 20a and 20b, management procedures would become complicated if the super relay server devices 20a and 20b were to be accessed by the normal relay server devices 30c and 30d connected to the display terminal devices 1e through 1h at the convenience stores CS2-1 and CS2-2 belonging to another franchise chain.
  • the relay-capable server devices are the super relay server devices 20 which act as the connection-capable relay server devices and which cache the creative data desired to be relayed from the viewpoint of the normal relay server devices 30.
  • the relay-determined server devices are the super relay server devices 20 which, from the viewpoint of the normal relay server devices 30, actually relay creative data when selected from among the relay-capable server devices.
  • the super relay server devices 20a and 20b can act as the relay-capable server devices and relay-determined server devices with regard to the chain of convenience stores CS1-1 and CS1-2 in Fig. 1 .
  • the above-mentioned schedule unit 12 makes the following decisions when determining the URL as the acquisition destination of given creative data in a play list:
